... PUL2 catalog contains original absolute proper motions of 59646 stars in 149 fields with galaxies. ... Mean errors of relative proper motions in PUL2 catalog is 5.5 mas/year. ... The external mean error of one relative proper motion of a bright star of PUL2 catalog is 9 mas/year for both of coordinates. ... After issue of UCAC2 catalog, we decided to improve accuracy of proper motions, using Pul-3 coordinates (of 1950s) as the first epoch, and UCAC2 coordinates as the second epoch. ...

Еще совсем недавно приобрести какую-либо оптику, пригодную для изготовления достаточно мощного телескопа хорошего качества было крайне трудно, почти невозможно, особенно любителям, живущим на периферии. ... Но начинать нужно с малого - с изготовления 100 - 150 мм зеркала, которое может быть основой для конструирования хорошего "ньютоновского" рефлектора. ... Поверхность одиночного зеркала способна строить неискаженное изображение светящейся точки ("звезды") только, если она имеет форму параболоида. ...
